1. Product description
Your solar controller is a microprocessor-based controller, for control of solar energy systems with one collec-
tor array and one storage reservoir. The pump is controlled so as to optimise the heat energy obtained from
the solar collector array, according to the solar irradiation and the temperatures which arise in the solar energy
system. With the heat energy thus obtained, one storage reservoir can be loaded, e.g. a domestic water
storage tank or a swimming pool.
1.1. Features and functions
Large illuminated display (LCD) with universally understandable symbols
All key system data at a glance
Easy operation and programming
Modern design in a compact housing for wall-mounting
Predefined system layout
Temperature difference control of a solar energy system with one collector array and one storage reservoir
Low-flow concept for optimal stratified loading
Frost protection function and protection from overheating for collectors and storage reservoirs
Thermostat and temperature comparison

DANGER
The controller may only be installed and operated in:
Protection degree
Danger of electrocution!
The controller is to be assembled, electrically installed, commissioned, inspected and repaired by
trained, competent and authorised persons (qualified electricians as per DIN VDE 1000-10 and
BGV A3) only!
Observe all applicable guidelines and regulations of the local electricity supplier!
Before beginning installation or repair work on electrical equipment, always ensure complete
disconnection from the mains and secure against reactivation!
Do not work on live parts!

5. Installing and connecting the controller
5.1. Proceed as follows – step by step
1. Check whether you wish to use additional functions (see 5.2. Possible additional functions and 10.
2. Check whether the desired additional functions can be realised, i.e. whether there are free sensors and
3. Install the controller at a suitable location and realise the electrical connections (see 5.6. Installing the
4. Install the required sensors (see 5.8. Installing the collector sensor and storage reservoir sensor).
5. Connect the required sensors to the controller and assign the relays according to your requirements
6. Switch on the controller by pressing and holding the button for at least 5 seconds.
7. Familiarise yourself with the controller’s menu navigation (see 6.1. Front view of the controller with
8. Configure any additional functions (see 10. Setting the additional functions).
9. Record your settings in the respective sections of this commissioning manual under “Selection”
Thoroughly check whether the packaging or the controller shows any sign of damage.
Transport the controller in the original packaging only.
If the controller falls, even from a low height, it may get damaged.
Prevent impact and extreme temperatures (below 0 °C or above + 50 °C) during transport and storage.
The controller may only be stored in its original packaging and in a dry environment.

5.2. Possible additional functions
This table shows you the additional functions which can be used. One relay can be assigned individually.
* Free relay required
** For these functions, it is also possible to use a relay which is already assigned.
5.3. Relay connector assignment
A solar pump must be connected to relay R1. The relay R2 is free and can be assigned individually.
5.4. Sensor connector assignment
The following table shows whether the selected additional functions can be realised:
F1 must be connected to the collector array
F2 is free and can be assigned individually
F3 can be connected to the upper part of the storage reservoir, otherwise it can be
assigned individually
F4 must be connected to the lower part of the storage reservoir
For the additional functions thermostat and temperature comparison the sensors can be configured freely and
activated on the specialised mechanic level.
